asp.net serialization and deserialization demo _ Practical Tips

What is serialization?
---. Net's run-time environment is used to support the mechanism of user-defined type fluidization. It is the process of storing the state of an object instance to storage media. In this procedure, the public and private fields of the object, as well as the name of the class, including the assembly in which the class resides, are converted to a byte stream, which is then written to the data flow. When the object is deserialized later, the exact same copy of the original object is created.
Purpose of Serialization:
1, in some form of storage to make the custom object persistent;
2. Transfer objects from one place to another.
Essentially, the serialization mechanism converts the value of a class to a generic (that is, continuous) byte stream, which can then be written to a disk file or to any other streaming target. To actually write this flow, you use the serialize and deserialize methods in the classes that implement the IFormatter interface.
